DUMP-WAGON.

Specification of Letters Patent.

Patented Aug. 22, 1905.

Application led January 27, 1905. Serial No. 242,829.

the art to which it appertains to make and use the same.

The invention relates to that description of dump-wagons in which drop-doors hinged to the lower edges of the wagon sides form the bottom and are arranged to fall downwardly to drop the load.

The objects of the invention are to increase the capacity of the wagon-bod y, to strengthen and simplify its support upon the rear axle, and to provide a simple and eflicient form of windlassing device and ratchet therefor.

The invention consists in the inclined dropdoors and lower edges of the end-boards, in the bracket-formed supports for the body upon the rear axle, and in the ratchet device for operating the windlass for raising and lowering thedrop-doors and in the various forms of construction as hereinafter described, shown in the accompanying drawings, and specifically pointed out in the claims.

In the accompanying drawings, Figure 1 is a side elevation of the wagon-body embodying my improvements. Fig. 2 is an elevation of a portion thereof, showing the ratchet device and a brake device by means of which the contents of the wagon can be spread over the surface of the ground. Fig. 3 is a plan view of the operating-pawl. Fig. 3u is a plan view of brake-band. Fig. 4 is an enlarged rear end elevation of the device. Fig. 5 is a longitudinal section of the end of rear axle or "skein, showing the bracket connecting the same rigidly with the side-board of the wagon. Fig. 6 is a side view of a portion of .wagon side, showing end of axle or skein.

In the views, 1 is the wagon-body, the end.

boards 2 of which are inclined to extend backward at the upper end and are vertical for the lower portion thereof. The drop-doors 3 are shown hung for downward, outward, and upward movement outside the wagon-body similarly to the doors shown in a previous United States patent to me bearing No.7 7 2,049, and they incline downwardly toward the centerwhere they meet, as shown in Fig. 4. It will be seen also in this figure that the endboards slope downward toward the center at 4 in a corresponding angle, so that the dropdoors will close tightly thereon. This angular drop of the doors before opening enlarges the lower portion of the wagon-body, so that it is enabled to carry a much larger load and lower down than is possible with the rectangular body.

In order to rigidly support the rear-wheel axles upon the side-boards of the wagon since it is impossible in this class of Wagons to employ a reach, the axles or skeins thereon are secured to or integral with the metal brackets 5, which are bolted directly to the sides, as

`shown in Figs. 4, 5, and 6, thus obtaining the greatest possible support and firmness of construction and obviating the use of the unusu- .ally heavy timbers commonly employed for this purpose. In these figures. 7 represents the wooden axles inserted within the skeins 8, and the skeins are cast integrally with the brackets.

i Any desirable form of construction, however,

comes within the spirit of this invention.

The drop-doors are shown to be supported for closing and lowering by means of windlass-chains 9, which are attached to the ends of the doors at their outer edges. These chains pass through guiding-tubes 10 upon the end-boards of the wagon-body and which conform toits angular shape, so that the chains will not rub upon the rear axle or hang away from the body portion. The chains then pass over the windlass-shaft 1l at each end of the wagon-body. The windlass-shafts are shown mounted in the side-boards and in a single heavy bearing at the center of each end-board, which continues downwardly and serves to stiften the board. On one side of the Wagon sprocket-wheels 12 upon the outer ends of these windlass-shafts are connected by a chain 13 to insure uniform movement of the two windlasses. At their other ends the windlassshafts are supplied with ratchets 14, which are operated in unison by means of the bar 15, mounted longitudinally upon guides 16 on the outer side of the side-board and by means of main operating and holding pawls 17 and 18 and the lever 19, pivoted to the side-board, where it will be most accessible to the hand of the operator. Adouble ratchet device is employed whereby one pawl will hold the ratchet from revolving, while the other is being advanced to engage with another tooth in advance and comprises the longer or main operating-pawl 17, which is pivoted upon the sliding bar 15 at 19 and engages with a tooth nearly at the upper edge pawl.

wheel the upper pawl will engage and push back the ratchet and the lower pawl will en-l gage the ratchet and prevent its reverse movement as soon as the lever is released. To disengage the lower pawl and release the windlass, the lever is thrown forward and the lower pawl is moved forward by means of its vertical arm, which is engaged by the shoulder 22 upon the upper pawl. By working the pawls carefully the windlass can be stopped before the complete opening of the drop-doors and the device can be used to spread the contents of the wagon through the incomplete opening. The forward end of the upper pawl is spring-pressed at 24 for tension to insure' engagement of the pawl with the ratchetteeth.

In order to permit the operator to hold the doors open at any desired width of opening to enable him to spread or scatter the load over a large surface, a brake strap or band 25 is secured at one end to the side-board at 26 and its other end is brought over the ratchet-disk and secured over the upwardlyextended arm of the holding-pawl at 9,7, so that when both pawls are released the arm will tighten the band over the edge of the ratchetwheel and hold it from revolving as long as desired.

Having described the invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination with the side-boards of a dump-wagon of end-boards therefor, the

said end-boards slanting inwardly as far as the lower edges of the side-boards, and then extending vertically downward, a rear axle y"passing behind the rear end-board, a metal bracket secured to each side-board inthe rear of the end-boards and means for attaching the rear axle thereto, substantially as described.

' 2. The combination with a dump-wagon provided with drop-bottom doors, adapted to move downwardly and outwardly at their inner edges, of flexible means for closing said doors, at each end thereof, windlasses upon which said flexible means are wound, ratchets upon said windlasses, a sliding bar mounted upon the wagon-body adjacent to said windlasses, an operating-pawl pivoted thereon, a holding-pawl pivoted upon the wagon, and a lever for operating said sliding bar, the said operating-pawl being provided with a shoulder against which the said holding-pawl rests whereby said holding-pawl may be withdrawn from engagement with said ratchet by the action of the operatingpawl, substantially as described. l

j 3.
